I've done that. Surprise.

At my last place of work, some contractors were extending the (3 phase) building. Irish electricians (oh my god the worst nationality to choose) confused the old wire colours with the new ones and mistook a phase for neutral. Hence some sockets got two phases instead of a phase and neutral. The computers caught fire, a surge protector melted into a glob of molten plastic, there was an awful smell, and we got a huge insurance claim for 40 new computers. I fixed the "broken beyond repair" computers for 50p each by replacing a capacitor in the power supplies.
